1) Product Overview

The Programmable Blank LTE USIM 4G Card is designed for telecom operator testing, integration, and controlled deployments. It comes as a 3-in-1 SIM (Standard/Micro/Nano), so one card can fit most device types without changing inventory.

HKCARD ELECTRONICS CO.,LIMITED / HKCARD supplies both:

  • Blank LTE USIM cards (for your own personalization process), and
  • Personalized/programmed cards (you provide authorized data, HKCARD writes it into the SIM securely).

Note: The SIM card is delivered with the COS (Card Operating System) already installed, so you typically do not need to handle COS-level work. Most projects only require writing the operator data fields during personalization.

2) Key Specifications (Quick View)

  • Product Name: LTE Blank USIM Card
  • Product Type: SIM Cards (Blank / Programmable)

3) Writable Fields (Personalization Options)

Depending on your project requirements, the card can be written with key parameters such as:

  • ICCID
  • IMSI

  • PIN / PUK
  • ADM

If you already have your own data and rules, HKCARD can write the required fields according to your provided specifications.

4) SIM Size: Standard, Micro, Nano (3 in 1)

This LTE USIM is supplied as a triple-format punch card, covering:

  • Standard SIM (2FF / Mini)
  • Micro SIM (3FF)
  • Nano SIM (4FF)

This format is widely used for:

  • device labs and test benches
  • routers / CPE / M2M terminals
  • POS devices
  • trackers and industrial gateways

5) Network Support: LTE / WCDMA / GSM

This USIM is compatible with common cellular environments:

  • 4G FDD LTE for modern LTE networks
  • WCDMA for 3G fallback scenarios (where still used)
  • GSM for basic 2G compatibility needs

If your devices require specific band or profile behavior, share your target region and device model so HKCARD can confirm suitability before shipment.

6) Delivery Options from HKCARD

Option A — Blank SIM Cards

Best for customers who have their own tools/process and want to manage personalization internally.

Option B — HKCARD Personalization Service

Best for customers who want ready-to-use SIMs. You provide the authorized data (ICCID/IMSI/etc.), and HKCARD programs the SIM accordingly.

SIM Tool (On Request)

A SIM tool can be provided on request depending on your workflow and quantity. Tell HKCARD how you plan to write and verify the cards.

7) Typical Use Cases

  • Telecom operator integration and controlled trials
  • Device QA testing (network attach, data sessions, stability checks)
  • Production validation for cellular hardware
  • Lab development where repeatable SIM behavior is needed

8) What to Send When Requesting a Quote
